No, the overwhelming majority of Americans are still routinely circumcised in 2022. Around 56-58% are cut out of the maternity ward and then 10% to 20% more afterwards in clinics and private practioners. Hence a 66-78% incidence and ~80% prevalence.
I'm not sure how accurate this is.
A CDC survey of hospitals from 2012 (over 10 years ago) found that it was around 55% of newborns on average, with it varying heavily by region. Lowest on the west coast, highest in the midwest.
The trend has been consistently dropping for the past several decades, so it wouldn't surprise me if it was 50% or less of boys being born in 2023.
I seriously doubt that 10-20% of parents care enough to get it done in private clinics after leaving the hospital.
The prevalence of adult men who are cut in the US is about 80% on average, true. But that has nothing to do with kids being born now.
The overwhelming majority of Gen Z, Millennial, and even a lot of Gen X parents I've talked to see no good reason to get it done, and the American Academy of Pediatrics directly says they don't recommend it.
